Abstract
The invention provides a gap-butt amorphous core with noise reduction function of epoxy coating. The gap-butt amorphous core is formed by packing a plurality of amorphous core plates; the amorphous core plates are divided into a plurality of core plate groups; the two ends of one core plate are butted at the bonding land of the core, a micro seam with equivalent width inside and outside is formed in the middle of the core plate, and the micro seams of any core plate group have a distance with the micro seams of the adjacent core plate group along the tangential direction of the amorphous core; the epoxy coating is coated at least on part of the area of the front end surface and the back end surface of the amorphous core. The gap-butt amorphous core of the invention can effectively prevent the magnetic resistance at the bonding position from being increased greatly and is beneficial to enhancing the intensity of the core, reducing the noise, ensuring the transmission of magnetic flux and improving the property of the amorphous core. In addition, the gap-butt amorphous core can be mainly used in transformers.
Description
Technical field
The present invention relates to a kind of gap dock amorphous core of noise reduction function of epoxy coating, mainly can be used for the amorphous core in the transformer.
Technical background
For coil being enclosed within on the amorphous core, at least one self joint usually will be set on amorphous core, leave seam at joint, from this seam amorphous core is opened and to be taken the shape of the letter U, just can be enclosed within on two arms of this U-shaped by coil, again join to together after the bending at two ends then, form the rectangle amorphous core U-shaped.If directly with the two ends butt joint, the amorphous core of joint is interrupted at joint, will produce very big magnetic resistance, influence the transmission of magnetic flux, therefore need improve engaging structure Moments shape.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of gap dock amorphous core of noise reduction function of epoxy coating, adopt this connected structure can prevent increasing considerably of magnetic resistance effectively, guarantee the transmission of magnetic flux, and help reducing noise.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of gap dock amorphous core of noise reduction function of epoxy coating, form by the folded system of several layers amorphous core sheet, described amorphous core sheet is divided into some lamination groups, dock mutually in the joint district of iron core at the two ends of same lamination group, small seam of middle formation, the small seam of any one lamination group with the small seam of adjacent lamination group on the tangential direction of amorphous core at a distance of a distance, be coated with epoxy coating to the small part area on the front/rear end of this amorphous core.
The invention has the beneficial effects as follows: owing on the front/rear end of iron core, be provided with epoxy coating, each lamination is bonded together, make it and to scatter, improved bulk strength unshakable in one's determination thus, reduced noise by epoxy coating; Because the epoxy resin that adopts has certain pliability, can not cause excessive stress on iron core; Because the small seam of different lamination groups is not together, any one small seam is all covered by the amorphous core sheet of adjacent lamination group, realized the connection of this small seam by the amorphous core sheet of adjacent lamination group, reduced the influence of seam thus effectively, improved the performance of amorphous core the magnetic flux transmission capacity; Because these small seams are wide, can be controlled in the minimum scope according to machining accuracy, therefore guaranteed seam to be limited in minimum to the influence of magnetic flux conductive, avoided occurring because the seam between the same lamination group two ends that each amorphous core leaf length in the same lamination group equates to occur is the problem of wedge shape expansion at certain condition.
Description of drawings
Fig. 1 is that the master who the present invention relates to inner amorphous core chip architecture looks schematic diagram;
Fig. 2 is the schematic side view that the present invention relates to the front/rear end coating.
Embodiment
Referring to Fig. 1, the invention provides a kind of gap dock amorphous core of noise reduction function of epoxy coating, form by the folded system of several layers amorphous core sheet, described amorphous core sheet is divided into some lamination groups, dock mutually in the joint district of iron core at the two ends of same lamination group, small seam 1 of middle formation, the small seam of any one lamination group with the small seam of adjacent lamination group on the tangential direction of amorphous core at a distance of a distance, be coated with epoxy coating 2 to the small part area on the front/rear end of this amorphous core.Because the existence of displacement between this small seam, the amorphous core sheet of adjacent lamination group must be overlapped on this seam.
Described epoxy coating can cover does not need all areas of taking apart on the end face of iron core, also can cover the emphasis part of influence bulk strength unshakable in one's determination and noise, can also adopt the mode of bar shaped coating, the bar shaped epoxy coating at the some coupling parts of coating or whole amorphous core sheet edges on end face of iron core, these bar shaped epoxy coatings are coupling part or whole edges of amorphous core sheets on end face of iron core, both arrive fixedly amorphous core sheet purpose, saved the consumption of epoxy resin again.
The distance of small seam on the amorphous core tangential direction of described adjacent lamination group is identical.
The small seam of described each lamination group is distributed on same the oblique line.
The small seam of described each lamination group is alternately distributed on the oblique line of two symmetries, and the distance between these two oblique lines enlarges from inside to outside gradually.
The small seam of described lamination group is in the certain area coverage of a side of amorphous core, from inside to outside along definite tangential direction of amorphous core from inside to outside along definite tangential direction cycle arrangement of amorphous core, both from the starting point (point in the middle of can being usually, also can be that this zone is in the starting point on this tangential direction) sequence arrangement on this tangential direction, after being aligned to this zone finishing line, return this regional starting line again along this tangential direction sequence arrangement, so circulation has repeatedly all been arranged until described small seam.This arrangement mode, be adapted to the many situations of amorphous core sheet number of packet, and can make on the amorphous core tangential direction, to have bigger distance between the adjacent small seam,, improve the amorphous core performance by increasing the distance and the number of packet that increases the amorphous core sheet on the tangential direction.
For the small seam at the small seam that guarantees each lamination group two ends and each amorphous core sheet two ends is wide, need the sheared length of each amorphous core sheet to determine according to this amorphous core sheet position on amorphous core.From inside to outside, the length of each amorphous core sheet increases successively, to adapt to the variation that different amorphous core sheets place is positioned at girth.By this control mode, can eliminate because the problem that each small seam in amorphous core sheet two ends that each amorphous core leaf length equates to cause in the same lamination group increases gradually helps to improve the amorphous core performance.
